[0001] This application is a continuation of International
Application No. PCT/CN2018/106037, filed on Sep. 17, 2018, which
claims priority to Chinese Patent Application No. 201710900295.1,
filed on Sep. 28, 2017. The disclosures of the aforementioned
applications are hereby incorporated by reference in their
entireties.
TECHNICAL FIELD
[0002] This application relates to the field of mobile
communications technologies, and in particular, to a measurement
method and an apparatus.
BACKGROUND
[0003] In a mobile communications system, a network transmits a
measurement configuration; user equipment (UE) performs measurement
based on the measurement configuration, and determines whether
reporting of a measurement report needs to be triggered; and if
yes, the user equipment reports the measurement report to the
network, and the network performs mobility decision, carrier
management, or the like based on the measurement report.
[0004] In a long term evolution (LTE) standard, when a primary cell
(PCell) signal quality of UE is higher than s-measure, it indicates
that a serving cell signal is sufficiently strong. In this case,
the UE may continue to perform serving cell measurement, but stop
performing measurement on intra-frequency, inter-frequency, and
inter-RAT neighboring cells, to save power for the UE.
SUMMARY
[0005] This application provides a measurement method and an
apparatus, to flexibly configure a measurement configuration of a
terminal, thereby further implementing balance between power saving
and performance of UE.
[0006] According to a first aspect, this application provides a
measurement method, and the method may be performed by a terminal
or a chip in a terminal. The method includes: receiving a
measurement configuration from a base station, where the
measurement configuration includes indication information, the
indication information is used to indicate a relationship between
neighboring cell measurement of a terminal and configured s-measure
of the terminal, and s-measure is used by the terminal to perform
no neighboring cell measurement when signal quality of a primary
cell is higher than or equal to s-measure; and performing the
neighboring cell measurement based on the indication information.
In the method, the indication information is carried in the
measurement configuration, to indicate the relationship between the
neighboring cell measurement of the terminal and configured
s-measure of the terminal, so that the terminal can perform the
neighboring cell measurement based on the indication information.
In the method, the indication information may be carried in the
measurement configuration, and the indication information indicates
the relationship between the neighboring cell measurement of the
terminal and configured s-measure of the terminal, so that flexible
configuration of the measurement configuration is implemented.
[0007] In a possible design, that the indication information is

measurement of a terminal and configured s-measure of the terminal
includes: the indication information indicates ignoring s-measure
during the neighboring cell measurement; and the performing the
neighboring cell measurement based on the indication information
includes: performing the neighboring cell measurement when the
signal quality of the primary cell in which the base station
provides a service to the terminal is higher than s-measure, where
the base station includes a primary base station or a secondary

inter-RAT measurement of the terminal when the signal quality of
the primary cell in which the base station provides a service to
the terminal is higher than s-measure. In this method, the
indication information may indicate ignoring s-measure during the
inter-RAT measurement of the terminal. Therefore, when the signal
quality of the primary cell in which the base station provides a
service to the terminal is higher than s-measure, the terminal
performs only a part of the neighboring cell measurement, that is,
performs only the inter-RAT measurement, thereby achieving balance
between UE power saving and UE performance.

perform uplink and downlink communication, to support high-speed
data transmission. Among the plurality of cells, one is a primary
cell (PCell), and another is a secondary cell (SCell).
[0052] Based on the carrier aggregation, cell aggregation between
two base stations is further introduced, and is referred to as dual
connectivity (DC). That is, the carrier aggregation is supported
for a plurality of cells served by the two base stations, so that a
user can have better user experience. For UE, one cell is a master
eNodeB (Master eNB, MeNB), and another cell is a secondary eNodeBs
(Secondary eNB, SeNB). In addition, a base station in which the
PCell is located is a primary base station, and the primary base
station undertakes more control functions. A serving cell served by
a secondary base station has a primary secondary cell (PSCell), and
another serving cell is an SCell.
[0053] A measurement configuration transmitted by the base station
to the terminal usually includes: a measurement object
configuration (measObjectConfig), a report configuration
(reportConfig), and a measurement identification (ID) configuration
(measIDConfig).
[0054] The measurement object configuration mainly includes a
measurement object, and the measurement object mainly includes a
frequency of a to-be-measured cell, a configuration related to
generation of a cell measurement value, and the like.
[0055] The report configuration includes a measurement event and a
configuration related to triggering of a measurement report, and
the like. For example, a configuration measurement event A3
indicates that quality of service of a neighboring cell is one
offset value higher than that of a serving cell.
[0056] The measurement ID configuration corresponds to the
measurement object and the report configuration. That is, the
measurement object and the report configuration are combined to
generate a measurement task. It may also be understood that one
measurement ID corresponds to one measurement task.
[0057] The following provides an example for description with
reference to a specific example.
[0058] For example, the measurement configuration transmitted by
the base station to the terminal is:
TABLE-US-00001 { Measurement ID configuration 1 {MeasID 1
(reportConfig ID 1, objectID 1)} Measurement ID configuration 2
{MeasID 2 (reportConfig ID 1, objectID 2)} Measurement ID
configuration 3 {MeasID 3 (reportConfig ID 2, objectID 1)}
Measurement ID configuration 4 {MeasID 4 (reportConfig ID 2,
objectID 2)} Measurement ID configuration 5 {MeasID 5 (reportConfig
ID 3, objectID 1)} Measurement ID configuration 6 {MeasID 6
(reportConfig ID 3, objectID 2)} Measurement object configuration 1
{objectID 1 (f1)} Measurement object configuration 2 {objectID 1
(f2)} Report configuration 1 {reportConfig ID 1 (A1)} Report
configuration 2 {reportConfig ID 2 (B1)} Report configuration 3
{reportConfig ID 3 (A1)} s-measure }
[0059] The foregoing measurement configuration includes two
measurement object configurations that are respectively represented
by objectID 1 and objectID 2, and respectively correspond to
measured frequencies f1 and f2. The measurement configuration
includes three report configurations that are respectively
represented by reportConfig ID 1 to reportConfig ID 3, and
respectively correspond to measurement events A1, B1, and A1. The
measurement configuration further includes six measurement ID
configurations that are respectively represented by MeasID 1 to
MeasID 6, and respectively correspond to six measurement tasks.
Each measurement task corresponds to one measurement object and one
measurement event. For details, refer to the foregoing description.
Further, the measurement configuration further includes configured
s-measure.
[0060] The quality threshold s-measure is introduced mainly for
saving power of the UE, s-measure is a threshold configured by a
network, and s-measure is used by the terminal to perform no
neighboring cell measurement when signal quality of a primary cell
is higher than or equal to s-measure.
[0061] When the base station is a primary base station, the primary
cell is a primary cell (PCell) of the primary base station. When
the base station is a secondary base station, the primary cell is a
primary secondary cell (PSCell) of the secondary base station. In
the prior art, when PCell signal quality of a terminal is higher
than or equal to s-measure, the terminal does not perform
measurement on any intra-frequency, inter-frequency, and inter-RAT
system neighboring cell. However, this measurement method has some
problems. For example, as shown in FIG. 1, in an EN-DC scenario,
according to the prior art, when PCell signal quality of an LTE
base station accessed by a terminal is higher than or equal to
s-measure, the terminal does not perform measurement on any
inter-frequency system and inter-RAT system neighboring cell, so
that the terminal does not report a measurement report of an NR
cell. The LTE base station does not receive the measurement report
of the NR cell reported by the terminal, in this way, the LTE base
station cannot add a cell of an NR base station. In other words,
the NR base station cannot be used as a secondary base station.
Consequently, the UE cannot use the NR cell, reducing performance
of the UE.
[0062] To resolve the foregoing problems, as shown in FIG. 2,
embodiments of this application provide a measurement method. On a
terminal side, the method may be performed by a terminal or a chip
of a terminal, and on a base station side, may be performed by a
base station or a chip of a base station. The following embodiment
is described by using interaction between a base station and a
terminal as an example.
[0063] It should be noted that the measurement method in this
application may be applicable to an application scenario in which
EN-DC is configured, but is not limited thereto. For example, the
measurement method in this application may alternatively be
applicable to carrier management inside an NR system. The method
includes the following steps.
[0064] Step 201. The base station generates a measurement
configuration.
[0065] The measurement configuration generated by the base station
includes a measurement object configuration, a report
configuration, and a measurement ID configuration. For details,
refer to the foregoing description. The measurement configuration
further includes s-measure.
[0066] Further, in this application, the measurement configuration
further includes indication information, and the indication
information is used to indicate a relationship between neighboring
cell measurement of the terminal and configured s-measure of the
terminal.
[0067] Specifically, the relationship that is between the
neighboring cell measurement of the terminal and configured
s-measure of the terminal and that is indicated by the indication
information may be understood as whether the neighboring cell
measurement of the terminal is related to configured s-measure of
the terminal, or may be understood as whether configured s-measure
of the terminal can be ignored during the neighboring cell
measurement of the terminal.
[0068] The following describes different cases.
[0069] Case 1. The indication information indicates ignoring
s-measure during the neighboring cell measurement of the
terminal
[0070] That the indication information indicates ignoring s-measure
during the neighboring cell measurement may also be understood as
that whether the terminal performs the neighboring cell measurement
is not related to s-measure. In other words, no matter whether
quality of a PCell measured by the terminal is higher than, lower
than, or equal to s-measure, the neighboring cell measurement
performed by the terminal is not affected.
[0071] Case 2. The indication information indicates that s-measure
cannot be ignored during the neighboring cell measurement of the
terminal
[0072] That the indication information indicates that s-measure
cannot be ignored during the neighboring cell measurement may also
be understood as that whether the terminal performs the neighboring
cell measurement is related to s-measure. For example, in an
implementation, when signal quality of the PCell measured by the
terminal is higher than s-measure, the terminal may stop performing
the neighboring cell measurement.
[0073] Step 202. The base station sends the measurement
configuration to the terminal, and the terminal receives the
measurement configuration from the base station.
[0074] Optionally, when the terminal is in a radio resource control
(RRC) connected mode, the base station sends the measurement
configuration to the terminal. It should be noted herein that the
measurement object configuration, the report configuration, the
measurement ID configuration, s-measure, and the indication
information that are included in the measurement configuration are
not limited to being sent to the terminal in one RRC message, and
may alternatively be sent to the terminal in a plurality of RRC
messages in sequence.
[0075] Step 203. The terminal performs the neighboring cell
measurement based on the indication information in the measurement
configuration.
[0076] After receiving the measurement configuration, the terminal
obtains a measurement ID in the measurement configuration, and one
measurement ID corresponds to one measurement task. The terminal
further obtains the indication information in the measurement
configuration, and the indication information may indicate that the
terminal performs the neighboring cell measurement for some or all
of the measurement tasks based on the indication information.
[0077] For the foregoing case 1, when the indication information
indicates ignoring s-measure during the neighboring cell
measurement of the terminal, specifically, measurement tasks, in
the measurement configuration, for which the neighboring cell
measurement is performed based on the indication information is
related to a manner in which the measurement configuration carries
the indication information. The following describes several
implementation methods.
[0078] Implementation method 1: The measurement configuration
carries the report configuration, and the report configuration
carries the indication information.
[0079] In the implementation method 1, the indication information
is used to indicate ignoring s-measure during the neighboring cell
measurement of the measurement task associated with the report
configuration.
[0080] Based on the foregoing example of the measurement
configuration, in the implementation method 1, the indication
information may be carried in the report configuration, for
example, the indication information is carried in a report
configuration 1, that is, the measurement configuration may be
shown as follows:
TABLE-US-00002 { Measurement ID configuration 1 {MeasID 1
(reportConfig ID 1, objectID 1)} Measurement ID configuration 2
{MeasID 2 (reportConfig ID 1, objectID 2)} Measurement ID
configuration 3 {MeasID 3 (reportConfig ID 2, objectID 1)}
Measurement ID configuration 4 {MeasID 4 (reportConfig ID 2,
objectID 2)} Measurement ID configuration 5 {MeasID 5 (reportConfig
ID 3, objectID 1)} Measurement ID configuration 6 {MeasID 6
(reportConfig ID 3, objectID 2)} Measurement object configuration 1
{objectID 1 (f1)} Measurement object configuration 2 {objectID 1
(f2)} Report configuration 1 {reportConfig ID 1 (A1), indication
information} Report configuration 2 {reportConfig ID 2 (B1)} Report
configuration 3 {reportConfig ID 3 (A1)} s-measure }
[0081] Because the measurement ID configuration 1 and the
measurement ID configuration 2 include the reportConfig ID 1, the
measurement task associated with the report configuration 1 is the
measurement ID configuration 1 and the measurement ID configuration
2. Therefore, when the indication information is carried in the
report configuration 1, the indication information indicates that a
measurement task corresponding to the measurement ID configuration
1 and a measurement task corresponding to the measurement ID
configuration 2 ignore s-measure during the neighboring cell
measurement.
[0082] Implementation method 2: The measurement configuration
carries the measurement object configuration, and the measurement
object configuration carries the indication information.
[0083] In the implementation method 2, the indication information
is used to indicate ignoring s-measure during the neighboring cell
measurement of the measurement task associated with the measurement
object configuration.
[0084] Based on the foregoing example of the measurement
configuration, in the implementation method 2, the indication
information may be carried in the measurement object configuration,
for example, the indication information is carried in a measurement
object configuration 1, that is, the measurement configuration may
be shown as follows:
TABLE-US-00003 { Measurement ID configuration 1 {MeasID 1
(reportConfig ID 1, objectID 1)} Measurement ID configuration 2
{MeasID 2 (reportConfig ID 1, objectID 2)} Measurement ID
configuration 3 {MeasID 3 (reportConfig ID 2, objectID 1)}
Measurement ID configuration 4 {MeasID 4 (reportConfig ID 2,
objectID 2)} Measurement ID configuration 5 {MeasID 5 (reportConfig
ID 3, objectID 1)} Measurement ID configuration 6 {MeasID 6
(reportConfig ID 3, objectID 2)} Measurement object configuration
1{objectID 1 (f1), indication information} Measurement object
configuration 2 {objectID 1 (f2)} Report configuration 1
{reportConfig ID 1 (A1)} Report configuration 2 {reportConfig ID 2
(B1)} Report configuration 3 {reportConfig ID 3 (A1)} s-measure
}
[0085] Because the measurement ID configuration 1 and the
measurement ID configuration 3 include the objectID 1, the
measurement task associated with the measurement object
configuration 1 is the measurement ID configuration 1 and the
measurement ID configuration 3. Therefore, when the indication
information is carried in the measurement object configuration 1,
the indication information indicates that a measurement task
corresponding to the measurement ID configuration 1 and a
measurement task corresponding to the measurement ID configuration
3 ignore s-measure during the neighboring cell measurement.
[0086] Implementation method 3: The measurement configuration
carries the measurement identification ID configuration, and the
measurement ID configuration carries the indication
information.
[0087] In the implementation method 3, the indication information
is used to indicate ignoring s-measure during the neighboring cell
measurement of the measurement task associated with the measurement
ID configuration.
[0088] Based on the foregoing example of the measurement
configuration, in the implementation method 3, the indication
information may be carried in the measurement ID configuration, for
example, the indication information is carried in a measurement ID
configuration 1, that is, the measurement configuration may be
shown as follows:
TABLE-US-00004 { Measurement ID configuration 1 {MeasID 1
(reportConfig ID 1, objectID 1), indication information}
Measurement ID configuration 2 {MeasID 2 (reportConfig ID 1,
objectID 2)} Measurement ID configuration 3 {MeasID 3 (reportConfig
ID 2, objectID 1)} Measurement ID configuration 4 {MeasID 4
(reportConfig ID 2, objectID 2)} Measurement ID configuration 5
{MeasID 5 (reportConfig ID 3, objectID 1)} Measurement ID
configuration 6 {MeasID 6 (reportConfig ID 3, objectID 2)}
Measurement object configuration 1 {objectID 1 (f1)} Measurement
object configuration 2 {objectID 1 (f2)} Report configuration 1
{reportConfig ID 1 (A1)} Report configuration 2 {reportConfig ID 2
(B1)} Report configuration 3 {reportConfig ID 3 (A1)} s-measure
}
[0089] Because the indication information is carried in a specific
measurement ID configuration, that is, the measurement ID
configuration 1, the indication information indicates that a
measurement task corresponding to the measurement ID configuration
1 ignores s-measure during the neighboring cell measurement.
[0090] Implementation method 4: The measurement configuration
carries the indication information, and the indication information
is not in the report configuration, the measurement object
configuration, and the measurement identification ID
configuration.
[0091] In the implementation method 4, the indication information
is used to indicate ignoring s-measure during the neighboring cell
measurement of specific measurement tasks of the terminal. These
specific measurement tasks may be specified in a standard protocol,
and do not need to be indicated by using RRC signaling. For
example, the protocol specifies that a specific measurement task is
inter-RAT (inter Radio Access Technology) measurement.
[0092] Based on the foregoing example of the measurement
configuration, in the implementation method 4, the indication
information may be carried in the measurement configuration, and
the measurement configuration may be shown as follows:
TABLE-US-00005 { Measurement ID configuration 1 {MeasID 1
(reportConfig ID 1, objectID 1)} Measurement ID configuration 2
{MeasID 2 (reportConfig ID 1, objectID 2)} Measurement ID
configuration 3 {MeasID 3 (reportConfig ID 2, objectID 1)}
Measurement ID configuration 4 {MeasID 4 (reportConfig ID 2,
objectID 2)} Measurement ID configuration 5 {MeasID 5 (reportConfig
ID 3, objectID 1)} Measurement ID configuration 6 {MeasID 6
(reportConfig ID 3, objectID 2)} Measurement object configuration 1
{objectID 1 (f1)} Measurement object configuration 2 {objectID 1
(f2)} Report configuration 1 {reportConfig ID 1 (A1)} Report
configuration 2 {reportConfig ID 2 (B1)} Report configuration 3
{reportConfig ID 3 (A1)} s-measure Indication information }
[0093] Because the indication information is carried in the
measurement configuration, and is not in the report configuration,
the measurement object configuration, and the measurement
identification ID configuration, in this implementation method, the
indication information is associated with a specific measurement
task of the terminal. That is, for example, when the protocol
specifies that the specific measurement task is inter-RAT
measurement, the indication information indicates that a
measurement task associated with the report configuration 2, that
is, the measurement ID configuration 3 and measurement ID
configuration 4 ignore s-measure during the neighboring cell
measurement.
[0094] When the indication information is used to indicate ignoring
s-measure during the inter-RAT measurement of the terminal, a
manner of performing the neighboring cell measurement is: when
signal quality of a primary cell PCell of the terminal is higher
than s-measure, still performing the inter-RAT measurement of the
terminal.
[0095] During the inter-RAT measurement of the terminal, if there
is an NR cell in a neighboring cell, signal quality of the NR cell
can be measured, so that reporting of a measurement report can be
triggered when a condition is met.
[0096] In the implementation method 1 to the implementation method
4, the indication information is used to indicate ignoring
s-measure during the neighboring cell measurement of the terminal.
Specifically, the indication information is used to indicate that a
measurement task associated with the indication information ignores
s-measure during the neighboring cell measurement.
[0097] In the example described in the foregoing implementation
method 1, the indication information is used to indicate that a
measurement task corresponding to the measurement ID configuration
1 and the measurement task corresponding to measurement ID
configuration 2 ignore s-measure during the neighboring cell
measurement. For other measurement tasks, that is, for measurement
tasks respectively corresponding to the measurement ID
configuration 3 to the measurement ID configuration 6, s-measure
cannot be ignored. In other words, when signal quality of a PCell
measured by the terminal is higher than s-measure, the terminal
stops performing neighboring cell measurement of these measurement
tasks.
[0098] In the example described in the foregoing implementation
method 2, the indication information is used to indicate that a
measurement task corresponding to the measurement ID configuration
1 and the measurement task corresponding to measurement ID
configuration 3 ignore s-measure during the neighboring cell
measurement. For other measurement tasks, that is, for neighboring
cell measurement of measurement tasks respectively corresponding to
the measurement ID configuration 2, and the measurement ID
configuration 4 to the measurement ID configuration 6, s-measure
cannot be ignored. That is, when signal quality of a PCell measured
by the terminal is higher than s-measure, the terminal stops
performing neighboring cell measurement of these measurement
tasks.
[0099] In the example described in the foregoing implementation
method 3, the indication information is used to indicate that the
measurement task corresponding to the measurement ID configuration
1 ignore s-measure during the neighboring cell measurement. For
other measurement tasks, that is, for neighboring cell measurement
of measurement tasks respectively corresponding to the measurement
ID configuration 2 to the measurement ID configuration 6, s-measure
cannot be ignored. That is, when signal quality of a PCell measured
by the terminal is higher than s-measure, the terminal stops
performing neighboring cell measurement of these measurement
tasks.
[0100] For a specific method in which the indication information is
used to indicate that s-measure cannot be ignored during the
neighboring cell measurement of the measurement task, the foregoing
methods of the implementation method 1 to the implementation method
3 may alternatively be used, and description by using an example is
not performed again.
[0101] In another case, if it needs to indicate ignoring s-measure
during neighboring cell measurement of a specific measurement task,
a method similar to the foregoing implementation method 4 may be
used, and description by using an example is not performed
again.
[0102] In the foregoing embodiment, the performing the neighboring
cell measurement based on the indication information may be:
performing the neighboring cell measurement when the signal quality
of the primary cell in which the base station provides a service to
the terminal is higher than s-measure. Alternatively, the
performing the neighboring cell measurement based on the indication
information may be understood as: performing the neighboring cell
measurement when the signal quality of the primary cell (PCell) of
the terminal is higher than s-measure.
[0103] In a possible implementation, for a specific method for
performing the neighboring cell measurement, refer to the prior
art. Details are not described again.
[0104] During specific implementation, the specific method for
performing the neighboring cell measurement may alternatively be:
when the signal quality of the primary cell (PCell) of the terminal
is higher than or equal to s-measure, performing the neighboring
cell measurement.
[0105] In the foregoing step 201 to step 203, the indication
information is carried in the measurement configuration, to
indicate the relationship between the neighboring cell measurement
of the terminal and configured s-measure of the terminal, so that
the terminal may perform the neighboring cell measurement based on
the indication information, thereby implementing flexible
configuration of the measurement configuration.
[0106] Further, the indication information may indicate ignoring
s-measure during the neighboring cell measurement of the terminal.
For example, if the indication information indicates ignoring
s-measure during the inter-RAT measurement of the terminal, when
the signal quality of the primary cell in which the base station
provides a service to the terminal is higher than s-measure, the
terminal performs only a part of the neighboring cell measurement,
that is, performs only the inter-RAT measurement and does not
perform intra-RAT measurement (for example, including
intra-frequency measurement and inter-frequency measurement),
thereby achieving balance between UE power saving and UE
performance.
[0107] In the foregoing implementation methods, based on
consideration of power saving, the base station may receive a
needed measurement report, to perform carrier management. For
example, an NR cell is added as a secondary base station, thereby
improving utilization of the NR cell, increasing a peak rate of a
user, and improving user experience.
[0108] Optionally, the following steps are further included.
[0109] Step 204. The terminal generates a measurement report and
sends the measurement report to the base station, and the base
station receives the measurement report from the terminal.
[0110] When measurement of the terminal meets a condition for
generating the measurement report, the measurement report is
generated and sent to the base station. For a specific
implementation process, refer to the prior art. Details are not
described again.
[0111] For example, referring to FIG. 1, if an LTE base station
indicates, by using the indication information of the measurement
configuration, that the neighboring cell measurement of the
terminal includes the inter-RAT measurement, after the base station
receives the measurement report, and if the base station determines
to add the NR cell as a serving cell of the terminal, EN-DC is
successfully configured, that is, the terminal works with the LTE
base station (a primary base station) and an NR base station (a
secondary base station) at the same time. A primary cell in LTE is
referred to as a primary cell (PCell) of the terminal, and a
primary cell in an NR base station is referred to as a primary
secondary cell (PSCell) of the terminal.
[0112] In an independent embodiment, after the NR base station is
added as the secondary base station of the terminal, the primary
base station and the secondary base station may separately transmit
measurement configurations to the terminal to perform neighboring
cell measurement, and the primary base station and the secondary
base station may separately transmit s-measure. S-measure 1
transmitted by the primary base station is specific to the PCell,
and s-measure 2 transmitted by the secondary base station is
specific to the PSCell.
[0113] For the primary base station, if the signal quality of the
PCell is higher than s-measure 1, the terminal does not perform the
neighboring cell measurement corresponding to the measurement
configuration transmitted by the primary base station. However, the
measurement configuration transmitted by the secondary base station
is not affected by s-measure 1, that is, the neighboring cell
measurement corresponding to the measurement configuration
transmitted by the secondary base station is still performed,
unless the PSCell is higher than s-measure 2. In this way,
s-measure transmitted by the primary base station and the secondary
base station affects only the measurement configurations
transmitted by the primary base station and the secondary base
station, thereby simplifying system complexity.
[0114] Optionally, for the primary base station, when the
measurement configuration sent by the primary base station includes
the indication information, for a specific implementation process,
refer to the method in the procedure shown in FIG. 2. To be
specific, the base station in the procedure shown in FIG. 2 is the
primary base station. For example, when the indication information
is used to indicate ignoring s-measure 1 during the neighboring
cell measurement of the terminal, that the terminal performs the
neighboring cell measurement may be: when the signal quality of the
primary cell (PCell) of the terminal is higher than s-measure 1,
performing the neighboring cell measurement. For another example,
when the indication information is used to indicate that s-measure
1 cannot be ignored during the neighboring cell measurement of the
terminal, that the terminal performs the neighboring cell
measurement may be: when the signal quality of the primary cell
(PCell) of the terminal is higher than s-measure 1, stopping
performing the neighboring cell measurement. For a specific method
for carrying the indication information, refer to the foregoing
description. Details are not described again.
[0115] For the secondary base station, if the (PSCell) is higher
than s-measure 2, the terminal does not perform the neighboring
cell measurement corresponding to the measurement configuration
transmitted by the secondary base station. However, the measurement
configuration transmitted by the primary base station is not
affected by s-measure 2. To be specific, the neighboring cell
measurement corresponding to the measurement configuration
transmitted by the primary base station is still performed, unless
the PCell is higher than s-measure 2.
[0116] Optionally, for the secondary base station, when the
measurement configuration sent by the secondary base station
includes the indication information, for a specific implementation
process, refer to the method in the procedure shown in FIG. 2. To
be specific, the base station in the procedure shown in FIG. 2 is
the secondary base station. For example, when the indication
information is used to indicate ignoring s-measure 2 during the
neighboring cell measurement of the terminal, that the terminal
performs the neighboring cell measurement may be: when the signal
quality of the primary secondary cell (PSCell) of the terminal is
higher than s-measure 2, performing the neighboring cell
measurement. For another example, when the indication information
is used to indicate that s-measure 2 cannot be ignored during the
neighboring cell measurement of the terminal, that the terminal
performs the neighboring cell measurement may be: when the signal
quality of the primary secondary cell (PSCell) of the terminal is
higher than s-measure 2, stopping performing the neighboring cell
measurement. In addition, for a specific method for carrying the
indication information, refer to the foregoing description. Details
are not described again.
[0117] It should be noted that the measurement for the secondary
base station is not affected by s-measure 1 configured by the
primary base station, and the measurement for the primary base
station is not affected by s-measure 2 configured by the secondary
base station. It may also be noted that the measurement for the
primary base station is affected only by s-measure 1 configured by
the primary base station, and the measurement for the secondary
base station is affected only by s-measure 2 configured by the
secondary base station.
[0118] In LTE, s-measure can only be configured as a reference
signal received power (RSRP) threshold. To be specific, an RSRP
measurement value of the PCell is compared with s-measure.
[0119] In the foregoing embodiments of this application, s-measure
may be configured as an RSRP threshold, or may be configured as a
signal to interference plus noise ratio (SINR) threshold. To be
specific, an s-measure configuration transmitted by the base
station may indicate a configured value on one hand, and may
further indicate a threshold type on the other hand, for example,
indicate that s-measure is specific to an SINR measurement
value.
[0120] Further, in a DC scenario, the primary base station and the
secondary base station may configure different types of s-measure
thresholds. For example, the primary base station configures
s-measure of an RSRP type, and the secondary base station
configures s-measure of an SINR type. Alternatively, the primary
base station configures s-measure of an SINR type, and the
secondary base station configures s-measure of an RSRP type.
[0121] Further, in the foregoing embodiments of this application,
s-measure may also be a threshold that is configured by the base
station and that is based on a measurement reference signal type,
where the measurement reference signal type is a synchronization
signal block (SS block) or a channel state information-reference
signal (CSI-RS).
[0122] Therefore, when both the threshold type and the measurement
reference signal type are considered, s-measure may be of the
following types.
[0123] S-measure is an RSRP threshold that is based on SS block
measurement, s-measure is an RSRP threshold that is based on CSI-RS
measurement, s-measure is an SINR threshold that is based on SS
block measurement, or s-measure is an SINR threshold that is based
on CSI-RS measurement.
[0124] S-measure may be s-measure configured by the primary base
station, or may be s-measure configured by the secondary base
station.
[0125] Further, in the foregoing embodiments of this application,
the indication information may alternatively be implemented by
using a threshold. When the indication information is a reference
threshold, the reference threshold is greater than s-measure.
[0126] The following separately describes the primary base station
and the secondary base station. The primary base station configures
s-measure 1 and a reference threshold 1, and the secondary base
station configures s-measure 2 and a reference threshold 2.
[0127] For the primary base station, when the signal quality of the
primary cell (PCell) of the terminal is higher than s-measure 1 and
is lower than the reference threshold 1, the primary base station
performs the neighboring cell measurement, and when the signal
quality of the primary cell (PCell) of the terminal is higher than
the reference threshold 1, the primary base station stops
performing the neighboring cell measurement.
[0128] For the secondary base station, when the signal quality of
the primary secondary cell (PSCell) of the terminal is higher than
s-measure 2 and is lower than the reference threshold 2, the
secondary base station performs the neighboring cell measurement,
and when the signal quality of the primary secondary cell (PSCell)
of the terminal is higher than the reference threshold 2, the
secondary base station stops performing the neighboring cell
measurement.
[0129] Further, in the foregoing embodiments of this application,
the indication information may alternatively be implemented by
using an offset value. When the indication information is an offset
value, the offset value is greater than 0.
[0130] The following separately describes the primary base station
and the secondary base station. The primary base station configures
s-measure 1 and a first offset value, and the secondary base
station configures s-measure 2 and a second offset value.
[0131] For the primary base station, when the signal quality of the
primary cell (PCell) of the terminal is higher than s-measure 1 and
is lower than a sum of s-measure 1 and the first offset value, the
primary base station performs the neighboring cell measurement, and
when the signal quality of the primary secondary cell (PSCell) of
the terminal is higher than the sum of s-measure 1 and the first
offset value, the primary base station stops performing the
neighboring cell measurement, and
[0132] For the secondary base station, when the signal quality of
the primary secondary cell (PSCell) of the terminal is higher than
s-measure 2 and is lower than a sum of s-measure 2 and the second
offset value, the secondary base station performs the neighboring
cell measurement, and when the signal quality of the primary
secondary cell (PSCell) of the terminal is higher than the sum of
s-measure 2 and the second offset value, the secondary base station
stops performing the neighboring cell measurement.
[0133] In an independent embodiment, the NR cell may be a quite
wide carrier. Due to a limitation of a terminal capability or the
like, when the NR cell is a serving cell of the terminal, the
terminal may work on only a part of bandwidth of the NR cell.
Therefore, one or more active bandwidth parts BWPs (Bandwidth Part)
may be configured for the terminal, and the active BWP of the
terminal may be quickly switched to another frequency band by using
physical layer signaling. A default BWP may also be configured for
the terminal by a network, as shown in FIG. 3.
[0134] When measuring the NR cell, the terminal actually measures a
reference signal, that is, an SS block and a CSI-RS. There may be a
reference signal on some BWPs, and there may be no reference signal
on some BWPs. When transmitting the measurement configuration, the
network may send a configuration of the reference signal, including
a frequency domain location, to the terminal, so that the terminal
can learn whether a reference signal exists on a currently active
BWP.
[0135] When there is a reference signal on an active BWP of the
terminal, the terminal may measure the reference signal on the
active BWP, and does not need to measure a reference signal outside
the active BWP. When the active BWP is changed to another frequency
band, the reference signal measured by the terminal is also changed
to a new active BWP, and provided that there is a reference signal
on one of a plurality of active BWPs of the terminal, in this case,
only the reference signal on the active BWP needs to be measured,
so that no measurement gap is needed when the terminal performs
measurement on the NR cell, thereby reducing impact on data
transmission. When there is no reference signal on the active BWP
of the terminal, the terminal may measure the reference signal on
the default BWP.
[0136] The solutions provided in this application are described
above mainly from a perspective of interaction between network
elements. It may be understood that, to implement the foregoing
functions, the network elements include corresponding hardware
structures and/or software modules for performing the foregoing
functions. A person skilled in the art should be easily aware that,
in combination with the examples described in the embodiments
disclosed in this specification, units and algorithms steps may be
implemented by hardware or a combination of hardware and computer
software in the present invention. Whether a function is performed
by hardware or hardware driven by computer software depends on
particular applications and design constraints of the technical
solutions. A person skilled in the art may use different methods to
implement the described functions for each particular application,
but it should not be considered that the implementation goes beyond
the scope of the present invention.
[0137] Based on a same inventive concept, an embodiment of this
application further provides a terminal 400. FIG. 4 is a schematic
structural diagram of the terminal. For ease of description, FIG. 4
shows only main components of the terminal. As shown in FIG. 4, the
terminal 400 includes a processor, a memory, a control circuit, an
antenna, and an input/output apparatus. The processor is mainly
configured to: process a communications protocol and communication
data, control the entire terminal, execute a software program, and
process data of the software program, for example, configured to
support the terminal in performing actions performed by the
terminal in the foregoing embodiment. The memory is mainly
configured to store software program and data. The control circuit
is mainly configured to perform conversion between a baseband
signal and a radio frequency signal and process the radio frequency
signal. The control circuit, together with the antenna, may also be
referred to as a transceiver that is mainly configured to send and
receive a radio frequency signal in an electromagnetic wave form.
The transceiver receives signaling sent by a base station. For
details, refer to the description in the foregoing related part.
The input/output apparatus such as a touchscreen, a display, or a
keyboard, is mainly configured to: receive data input by a user,
and output data to the user.
[0138] After the terminal is powered on, the processor may read the
software program in a storage unit, interpret and execute an
instruction of the software program, and process the data of the
software program. When data needs to be sent wirelessly, the
processor performs baseband processing on to-be-sent data, and then
outputs a baseband signal to a radio frequency circuit. After
performing radio frequency processing on the baseband signal, and
the radio frequency circuit sends a radio frequency signal in an
electromagnetic wave form by using the antenna. When data is sent
to the terminal, the radio frequency circuit receives the radio
frequency signal by using the antenna, converts the radio frequency
signal into the baseband signal, and outputs the baseband signal to
the processor. The processor converts the baseband signal into
data, and processes the data.
[0139] A person skilled in the art may understand that for ease of
description, FIG. 4 shows only one memory and only one processor.
Actually, the terminal may include a plurality of processors and a

baseband processor and a central processing unit. The baseband
processor is mainly configured to process the communications
protocol and the communication data. The central processing unit is
mainly configured to: control the entire terminal, execute the
software program, and process the data of the software program. The
processor in FIG. 4 integrates functions of the baseband processor
and the central processing unit. A person skilled in the art may
understand that the baseband processor and the central processing
unit may be alternatively processors independent of each other, and
are interconnected by using a technology such as a bus. A person
skilled in the art may understand that the terminal may include a
plurality of baseband processors to adapt to different network
standards, and the terminal may include a plurality of central
processing units to enhance a processing capability of the
terminal. The components of the terminal may be connected by using
various buses. The baseband processor may also be expressed as a
baseband processing circuit or a baseband processing chip. The
central processing unit may also be expressed as a central
processing circuit or a central processing chip. A function of
processing the communication protocol and the communication data
may be embedded into the processor, or may be stored in a storage
unit in a form of a software program, so that the processor
executes the software program to implement a baseband processing
function.
[0141] For example, in this embodiment of this application, the
antenna and the control circuit that have a sending and receiving
function may be considered as a transceiver unit 401 of the
terminal 400, and the processor having a processing function may be
considered as a processing unit 402 of the terminal 400. As shown

a receiving unit, and a component for implementing a sending
function in the transceiver unit 401 may be considered as a sending
unit. In other words, the transceiver unit 401 includes the
receiving unit and the sending unit. For example, the receiving
unit may also be referred to as a receiver machine, a receiver, a
receiver circuit, or the like, and the sending unit may be referred
to as a transmitter machine, a transmitter, a transmit circuit, or
the like.
[0142] Based on a same inventive concept, an embodiment of this
application further provides a base station 500. FIG. 5 is a

and a radio frequency unit 5012. The RRU 501 is mainly configured
to send and receive a radio frequency signal and convert the radio
frequency signal and a baseband signal. The BBU 502 is mainly
configured to perform baseband processing, control the base
station, and the like. The RRU 501 and the BBU 502 may be
physically disposed together, or may be physically disposed
separately, namely, in a distributed base station.
[0143] The BBU 502 is a control center of the base station, may
also be referred to as a processing unit, and is mainly configured
to implement a baseband processing function such as channel coding,
multiplexing, modulation, or spreading. For example, the BBU
(processing unit) may be configured to control the base station to
perform some actions performed by the base station in the foregoing
embodiment.
[0144] In an example, the BBU 502 may include one or more boards,
and a plurality of boards may jointly support a radio access
network of a single access standard, or may separately support
radio access networks of different access standards. The BBU 502
further includes a memory 5021 and a processor 5022. The memory
5021 is configured to store a necessary instruction and necessary
data. For example, the memory 5021 stores configuration information
of a random access preamble in the foregoing embodiment. The
processor 5022 is configured to control the base station to perform
a necessary action, for example, configured to control the base
station to perform the action performed by the base station in the
foregoing embodiment. The memory 5021 and the processor 5022 may
serve one or more boards. In other words, a memory and a processor
may be independently disposed on each board. Alternatively, a
plurality of boards may use a same memory and a same processor. In
addition, a necessary circuit is further disposed on each
board.

[0216] A person skilled in the art should understand that the
embodiments of this application may be provided as a method, an
apparatus (device), a computer-readable storage medium, or a
computer program product. Therefore, this application may use a
form of hardware only embodiments, software only embodiments, or
embodiments with a combination of software and hardware. They are
collectively referred to as "modules" or "systems".
[0217] This application is described with reference to the
flowcharts and/or block diagrams of the method, the apparatus
(device), and the computer program product according to this
application. It should be understood that computer program
instructions may be used to implement each process and/or each
block in the flowcharts and/or the block diagrams and a combination
of a process and/or a block in the flowcharts and/or the block
diagrams. These computer program instructions may be provided for a
general-purpose computer, a special-purpose computer, an embedded
processor, or a processor of another programmable data processing
device to generate a machine, so that the instructions executed by
a computer or a processor of another programmable data processing
device generate an apparatus for implementing a specific function
in one or more processes in the flowcharts and/or in one or more
blocks in the block diagrams.
[0218] These computer program instructions may alternatively be
stored in a computer-readable memory that can instruct the computer
or another programmable data processing device to work in a
specific manner, so that the instructions stored in the
computer-readable memory generate an artifact that includes an
instruction apparatus. The instruction apparatus implements a
specific function in one or more processes in the flowcharts and/or
in one or more blocks in the block diagrams.
[0219] These computer program instructions may alternatively be
loaded onto a computer or another programmable data processing
device, so that a series of operations and steps are performed on
the computer or the another programmable device, to generate
computer-implemented processing. Therefore, the instructions
executed on the computer or the another programmable device provide
steps for implementing a specific function in one or more processes
in the flowcharts and/or in one or more blocks in the block
diagrams.

to specific features and the embodiments thereof, clearly, various
modifications and combinations may be made to them without
departing from the scope of the present invention. Correspondingly,
the specification and accompanying drawings are merely example
description of the present invention defined by the appended
claims, and are considered as any of or all modifications,
variations, combinations or equivalents that cover the scope of the
present invention. Clearly, a person skilled in the art can make
various modifications and variations to the present invention
without departing from the spirit and scope of the present
invention. In this way, the present invention is intended to cover
these modifications and variations provided that they fall within
the scope of protection defined by the following claims and their
